Pump sizing aka adequate flow rate

[Master plumber]

So here is the story I have a 90 gallon reef tank on my first floor and a 40 gallon breeder tank in the basement in my office I am trying to combine the sumps for these two tanks in the basement next to my office now the major problem I am having is that I cannot find a pump to give me adequate gallons per hour to my 90 gallon display tank on the first floor
I am trying to just have one return pump from my sump to the other two tanks The second question is what is a acceptable gallon per hour flow rate for my 90 gallon tank everyone I ask online and locally gives me different answers the answer I most commonly get is more is better I am trying to shoot for 1000 gallons an hour as of right now I want to say my filtration is at about 600 gallons per hour any extra input would be greatly appreciated

As a note my main display tank to the sump is approximately 15 feet straight up from the pump

PanWorld 250PS External Aquarium Water Pump - 1900gph - Bulk Reef Supply
You might even be able to get away with the 200ps, depending on how much flow you need for other things.

Just the breeder small 20 refugium to follow but that's about it thinking desperate pump for that

Find out what the pw200 is after 15 feet of head and you will have a pretty good idea which pump you need.
